Abstract
The first asymmetric Ficini−Claisen rearrangement using chiral ynamides is described. At relatively low temperatures, the Ficini−Claisen rearrangement can be efficiently promoted by p-nitrobenzenesulfonic acid leading to high diastereoselectivity for a range of different allylic alcohols and chiral ynamides.
